I have no problem replace the switch. The new switch is different wiring setup on the housing switch and the instructions could be larger and the wires should be lable or colour the same wire as the original one. Having all white wires can be confusing if you are not an expert in the connection to the drill and the switch. I went online for better detail of the wiring diagram and it helped me to properly route the right wires. Drywall drill driver works great.
